We only do Disney every so often. I follow a lot of the same rules several have posted a list on to save money. And I do it because I don't know and don't feel comfortable not being frugal in daily life. I, too, grew up this way.
New cars only when the one I'm using stops working. Dh's truck he's had 8 years, I've had mine 3, but plan to keep for another 10 if I can
Shopping- my monthly grocery bill averages $250/month- because I watch circulars, sales, and stockpile when I can buy stuff dirt cheap or free. The only foods that get bought weekly around here are milk and bread and fresh vegetables.
I don't shop to shop. When I do, I buy clothes on the clearance aisles with coupons to purchase items very cheap.
I shop yard sales
I work. And hard, to occasionally get bonuses
I work the credit card system. All credit cards paid off monthly. Awesome credit. Open cards that give great opening rewards, hold on to them long enough to use and get the bonus (ie Disney rewards card, spend $500, get $200 back in Disney giftcard), then cancel within a year. I do this with other cards about once a year to get travel bonuses
Always shop online through ebates
Shop for travel through hotwire, etc... and use coupons from retailmenot.com to get an even better discount through those sites.
Just because its on sale, its not a deal
I don't take my kids places that cost $ except special occasions. We have enough free parks, splash pads, bike routes, etc we can do to avoid paying museum fees, aquarium fees, etc...
I pay for everything with credit cards, and take the reward points and purchase giftcards for places we go often.
Eating out once a month as a family, about once a week fast food.
Pack lunches. Cook at home.
At Disney: After obtaining gift cards through cc deals, Target giftcard/raise deals to pay for trip.
Pack at least 1 park meal, eat 1 at the hotel, 1 meal in park per day. My kids are much happier knowing they'll get to eat a PB&J than worrying what they might not like at the park anyhow.
I'm already gonna have to carry a small pack with an extra shirt or something for the kids, so an extra water bottle is not an issue.
(this last trip I was very thankful I pack extra outfits for the parks when my child got sick in the park and got his clothes dirty- I had something to move him right into)
Reuse Disney sling pack bag from 2011!
